Abstract
With nutrient solution culture,our experiments were conducted to investigate the effects on the content of K+,Na+ in roots and shoots of grafted watermelon (Citrullus vulgaris Schrad.,Lagenaria siceraria Standl. is rootstock) under salt stress. The findings show that,compared with own-root seedlings,the salt tolerant grafted seedlings accumulated Na+ mainly in the roots,and maintained higher level of K+ in the shoots,which indicated that grafted seedlings could absorb more K+ in the shoots and also maintain more Na+ in the roots. X-ray microanalysis of root transverse section in watermelon seedlings shows that roots endodermis of grafted watermelon could retain the transport of Na+ to stellar parenchyma vessels maintaining much Na+ in the roots whereas promote the flow of K+ to the shoots thus to keep higher [K+] [Na+] resulting grafted watermelon's ability of salt resistance.
